Cardiac Rhythm Disturbances in Heterotaxy Syndrome.

Pediatr Cardiol 2019 Mar 14. Epub 2019 Mar 14.

Department of Pediatrics, University of Tokyo Hospital, Tokyo, Japan.

Objective: Heterotaxy syndrome is associated with complex cardiac malformations and cardiac conduction system abnormalities. Those with right atrial isomerism (RAI) have dual sinus nodes and dual atrioventricular nodes predisposing them to supraventricular tachycardia (SVT). Those with left atrial isomerism (LAI) lack a normal sinus node and are at risk of sinus node dysfunction (SND) and atrioventricular block (AV block). Read More

A new combination of transcription factors increases the harvesting efficiency of pacemaker‑like cells.

Mol Med Rep 2019 Mar 6. Epub 2019 Mar 6.

Department of Cardiology, Renmin Hospital of Wuhan University, Wuhan, Hubei 430060, P.R. China.

Biological pacemakers that combine cell‑based and gene‑based therapies are a promising treatment for sick sinus syndrome or severe atrioventricular block. The current study aimed to induce differentiation of adipose tissue‑derived stem cells (ADSCs) into cardiac pacemaker cells through co‑expression of the transcription factors insulin gene enhancer binding protein 1 (ISL‑1) and T‑box18 (Tbx18). ADSCs were transfected with green fluorescent protein, ISL‑1, Tbx18 or ISL‑1+Tbx18 fluorescent protein lentiviral vectors, and subsequently co‑cultured with neonatal rat ventricular cardiomyocytes in vitro for 7 days.

Fetal dysrhythmias.

Best Pract Res Clin Obstet Gynaecol 2019 Jan 9. Epub 2019 Jan 9.

Royal Brompton and Harefield NHS Foundation Trust, Sydney Street, London, SW3 6NP, UK; Fetal Medicine Unit, St George's University Hospital, Blackshaw Road, London, SW17 0QT, UK; Molecular and Clinical Sciences Research Institute, St George's, University of London, Cranmer Terrace, London, SW17 0RE, UK. Electronic address:

Fetal dysrhythmias are common abnormalities, usually manifesting as irregular rhythms. Although most irregularities are benign and caused by isolated atrial ectopics, in a few cases, rhythm irregularity may indicate partial atrioventricular block, which has different etiological and prognostic implications. We provide a flowchart for the initial management of irregular rhythm to help select cases requiring urgent specialist referral. Read More

Cardiovascular Manifestations of Inflammatory Bowel Disease: Pathogenesis, Diagnosis, and Preventive Strategies.

Gastroenterol Res Pract 2019 13;2019:3012509. Epub 2019 Jan 13.

Department of Internal Medicine, "Grigore T. Popa" University of Medicine and Pharmacy, Iasi 700111, Romania.

Inflammatory bowel disease (IBD) refers to a group of chronic inflammatory diseases that targets mainly the gastrointestinal tract. The clinical presentation of IBD includes both gastrointestinal manifestations and extraintestinal manifestations (EIM). The reported cardiovascular manifestations in IBD patients include pericarditis, myocarditis, venous and arterial thromboembolism, arrhythmias, atrioventricular block, heart failure, endocarditis, valvulopathies, and Takayasu arteritis.

Lev's Syndrome: A rare case of progressive cardiac conduction disorder presenting to the emergency department.

Am J Emerg Med 2019 Jan 31. Epub 2019 Jan 31.

Emergency Medicine Department, Brooke Army Medical Center, Fort Sam Houston, TX, USA.

Lev's Syndrome is a rare, progressive cardiac conduction defect (PCCD) due to myocardial fibrosis first described by Maurice Lev in 1964. This condition, proposed to start in the fourth decade of life, involves a sclerotic fibro-fatty degeneration of the Bundle of His and Purkinje fibers, which Lev proposed caused increasing AV delay with age. With the prevalence of electrocardiogram (ECG) use in the emergency department (ED) for cardiac- and non-cardiac complaints, dysrhythmias can be incidentally found and confuse diagnosis and disposition.

Implantation of engineered conduction tissue in the rat heart.

Mol Med Rep 2019 Feb 5. Epub 2019 Feb 5.

Institute of Biomedical Engineering, Second Military Medical University, Shanghai 200433, P.R. China.

Engineered conduction tissues (ECTs) are cardiac conduction tissues fabricated in vitro to allow for more precisely targeted in vivo transplantation therapy. The transplantation of ECTs may be ideal for the treatment of atrioventricular conduction block and could have a significant impact on the future application of biological pacemakers. However, there is little published information regarding the conduction function of ECTs in vivo. Read More

Measurement of J-Tc along with QT-Interval Prolongation May Increase the Assay Sensitivity and Specificity for Predicting the Onset of Drug-Induced Torsade de Pointes: Experimental Evidences Based on Proarrhythmia Model Animals.

Cardiovasc Toxicol 2019 Feb 2. Epub 2019 Feb 2.

Department of Pharmacology, Toho University Graduate School of Medicine, 5-21-16 Omori-nishi, Ota-ku, Tokyo, 143-8540, Japan.

dl-Sotalol which can block both K channel and ß-adrenoceptor has been shown to prolong the J-Tc of electrocardiogram in beagle dogs but tended to shorten it in microminipigs, although the drug prolonged the QT interval in both animals under physiologically maintained experimental condition. In order to estimate how the changes in the J-Tc in the normal hearts would be reflected in the pathologic hearts, we compared proarrhythmic effects of dl-sotalol by using proarrhythmia models of beagle dogs and microminipigs, of which atrioventricular node had been ablated > 2 months and 8-9 weeks before, respectively (n = 4 for each species). dl-Sotalol in an oral dose of 10 mg/kg induced torsade de pointes in three out of four beagle dogs, which degenerated into ventricular fibrillation.

Indications for permanent pacing in dogs and cats.

J Vet Cardiol 2019 Jan 29. Epub 2019 Jan 29.

Clinica Veterinaria Malpensa, Viale Marconi 27, 21017 Samarate, Varese, Italy.

Pacemaker implantation is considered as a standard procedure for treatment of symptomatic bradycardia in both dogs and cats. Advanced second-degree and third-degree atrioventricular blocks, sick sinus syndrome, persistent atrial standstill, and vasovagal syncope are the most common rhythm disturbances that require pacing to either alleviate clinical signs or prolong survival. Most pacemakers are implanted transvenously, using endocardial leads, but rarely epicardial leads may be necessary. Read More

Novel Method for Assessment of His Bundle Pacing Morphology Using Near Field and Far Field Device Electrograms.

Circ Arrhythm Electrophysiol 2019 Feb;12(2):e006878

Division of Cardiac Electrophysiology, Rush University Medical Center, Chicago, IL (N.J.S., R.Z., R.T., P.S.S.).

Background: The 12-lead ECG is considered the gold standard to differentiate between selective (S), nonselective (NS) His bundle pacing (HBP), and right ventricular septal capture in routine clinical practice. We sought to assess the utility of device EGM recordings as a tool to identify the type of HBP morphology.

Methods: One hundred forty-eight consecutive patients underwent HBP with a 3830 Select Secure lead (Medtronic, Inc) at 3 centers between October 2016 and October 2017. Read More
